dlp vs. rear lcd projection. What's the diff?

I'm not an expert, owning neither yet but having shopped for both for well over a year. (Even got a letter publishing in S+V on it!) But...


LCD RP appeared to me to be worse at low-light scenes. For example (my specific example), the series Babylon 5 has dark blue and grey uniforms, in outer space, and the battleships (e.g. white star) are dimly lit. On an LCD RP, at a certain point everything just vanishes. You have ghost arms and hands and then a bit of a body, with a ghost head.


Also fast moving high-contrast images (think laser beams or a slapping hand) left trails briefly.


DLP didn't have that problem, and seemed more vivid also, but on some CGI scenes had an amazing amount of what I could only call "shimmer". No non-DLPs had this. It's possible this was equivalent to RBE, but showed particularly hard on this source - the scene is a rotating space ship, so your eye focus is constantly moving with the little blocks rather than staying on a given pixel.


Those are the big differences I noticed. Contrast (or better darks at any rate) favored DLP, lack of shimmer on CGI favored LCD, so I bought neither. But the differences between DLPs, for example, is bigger than the difference between LCD and DLP RPs. For SD on a high-res fixed-pixel unit, for example, I think scaling probably matters a lot more than the technology used to get the display up there, among contemporary technologies.


But again, I'm the least expert of anyone here. I just happened to be comparing those two specific technologies myself because I dread plasma burn-in.
